问题 After using beginUpdates() endUpdates() This method -> tableView.setContentOffset(_, animated:) // do not work Do not work after calling that 2 methods (even if I use timer), but works without them!

问题 I have a TableView embedded in NavigationController (and that's embedded in a TabBar Controller). I have a username button in each cell that segues to the user's profile.
